The minimum trench width shall be 1-½ times the pipe diameter plus twelve inches (12”). Installation of HDPE pipe shall be by methods approved by the Construction Engineer, and per the manufacturer’s recommendation. Methods other than approved shall not be allowed. Any installation of HDPE pipe by methods that are not approved shall be removed and reinstalled at the expense of the Contractor.; HDPE Storm Sewer Pipe – Televising Specifications: All HDPE storm sewer pipe being televised by private companies shall conform to the following set of standards: Videos may be submitted by Compact Disc (CD) or DVD.

Beginning and Ending structures shall be called out using the stationing and line number references as shown on the construction plans.; Televising will begin at the center of the upstream manhole and will run continuously to the center of the downstream manhole. The center of the upstream manhole shall be set at 0 ft and the video shall show the complete footage of each line. Any breaks or incontinuities in the video recording will result in the video being rejected and a new and complete video will need to be submitted.; Approximately one inch simulated flow shall be added to show flow grade. Camera shall be pulled in the same direction as the flow, unless approved in writing by the City Engineer’s office.
